Gini · Learn investing · 2026-10-29 · https://ginity.vn/en/blog/stocks-under-warning-control-suspension _Lead analyst: Đào Ngọc Bảo Linh · Finance and securities specialist · Ho Chi Minh City · 0932 439 639_ ## Key takeaways - Listing regulations define 5 oversight tiers: warning, control, trading restriction, temporary trading halt, and trading suspension. - Mandatory filing deadlines form core triggers: 15 days for warning, 30 days for control, 45 days for restriction, and six months for suspension. - The margin exclusion list for the fourth quarter of 2026 on HOSE disqualified 65 securities. When a listed company commits periodic reporting violations or undergoes financial deterioration, stock exchanges apply corresponding surveillance measures. In Vietnam, this enforcement framework is established under the [Listing and Trading Regulations for Listed Securities](https://luatvietnam.vn/chung-khoan/quyet-dinh-22-qd-hdtv-2026-ban-hanh-quy-che-niem-yet-va-giao-dich-chung-khoan-430733-d1.html) issued under Decision 22/QD-HDTV dated 16/03/2026 by the Board of Members of Vietnam Exchange, pursuant to authority under the [Securities Law](https://vanban.chinhphu.vn/?docid=198541&pageid=27160). The regulatory framework for market administration is detailed under [Decree 155/2020/ND-CP](https://vanban.chinhphu.vn/?docid=202222&pageid=27160) dated 31/12/2020 by the Government (as amended by Decree 245/2025/ND-CP). ## Five regulatory oversight tiers in the stock market Under Listing Decision 22/QD-HDTV, exchange surveillance applied to listed issuers is structured into 5 distinct tiers: - **Warning (Article 40):** Applied when an enterprise delays financial reporting past 15 days, breaches disclosure obligations 4 times or more within one calendar year, or records negative undistributed post-tax profit on audited financial statements. - **Control (Article 41):** Applied when audited annual or reviewed semi-annual reporting delays exceed 30 days, audited post-tax profit is negative for the two most recent years, or owner equity is negative on the latest financial statements other than audited annual statements pursuant to Point đ, Clause 1, Article 41. - **Trading restriction (Article 42):** Applied when filing delays exceed 45 days or information disclosure violations continue after entering control. Trading methods and permitted execution hours for restricted equities are conducted pursuant to Appendix III (Article 42.3). - **Temporary trading halt (Article 43):** An urgent administrative pause implemented when stock prices or trading volumes experience abnormal swings, when issuers carry out stock splits, share consolidations, or capital reductions, or upon request from the State Securities Commission. - **Trading suspension (Article 44):** Applied when reporting delays exceed six months, repeated violations persist after restriction, or the issuing firm has its enterprise registration certificate revoked. ## Mandatory deadlines and violation triggers Exchange surveillance decisions follow defined reporting delay timelines set out in Listing Decision 22/QD-HDTV: Delays exceeding 15 days: A listed security is placed under warning pursuant to Point g, Clause 1, Article 40 of Decision 22/QD-HDTV. Point h, Clause 1, Article 40 also specifies that an issuer committing information disclosure violations 4 times or more within a single calendar year enters warning status. Negative undistributed post-tax profit recorded on audited financial statements also triggers this tier. Delays exceeding 30 days: An issuer moves from warning to control status under Point g, Clause 1, Article 41 of Decision 22/QD-HDTV when audited annual or reviewed semi-annual financial statements are overdue by more than 30 days. Other legal grounds include negative post-tax profit for the two most recent audited years, or negative owner equity on the latest financial statements other than audited annual statements under Point đ, Clause 1, Article 41. On 06/05/2026, HOSE issued a decision transferring [DGC shares under control](https://vietstock.vn/2026/05/dgc-vao-dien-kiem-soat-nguy-co-bi-loai-khoi-vn30-830-1439072.htm) due to an audited financial filing delay exceeding 30 days beyond the deadline, [effective from 13/05/2026](https://vneconomy.vn/co-phieu-dgc-bi-chuyen-sang-dien-kiem-soat-tu-ngay-135.htm). Delays exceeding 45 days: The exchange transfers the stock into trading restriction under Point a, Clause 1, Article 42 of Decision 22/QD-HDTV. According to VnEconomy on 19/10/2026, HOSE announced that [PLP and VPG shares were placed under trading restriction](https://vneconomy.vn/co-phieu-lpl-va-vpg-bi-dua-vao-dien-han-che-giao-dich.htm) effective from 23/10/2026 for submitting their reviewed semi-annual financial statements for 2026 more than 45 days past the prescribed deadline. Delays extending beyond six months: Pursuant to Point a, Clause 1, Article 44 of Decision 22/QD-HDTV, an issuer delaying audited annual or reviewed financial reports by more than six months faces trading suspension. In addition, revocation of enterprise registration certificate directly triggers a trading suspension determination under Article 44. ## Comparison of the five oversight categories The table below outlines the rule articles, core violation grounds, and principal trading consequences for each supervision tier under existing regulations: | Oversight Tier | Rule Article | Main Violation Criteria | Primary Trading Impact | | :--- | :--- | :--- | :--- | | Warning | Article 40 | Reporting delay over 15 days; disclosure breaches 4 times a year; negative retained earnings | Warning tag recorded on system | | Control | Article 41 | Reporting delay over 30 days; negative post-tax profit for 2 audited years; negative equity | Control tag recorded on system | | Trading restriction | Article 42 | Reporting delay over 45 days; repeated disclosure infractions after control | Executed pursuant to Appendix III (Article 42.3) | | Temporary halt | Article 43 | Abnormal price or volume swings; stock splits; capital reduction; regulatory directive | Pursuant to exchange determination | | Trading suspension | Article 44 | Reporting delay over six months; revocation of enterprise registration certificate | Suspended by exchange determination | ## Margin trading exclusion list According to reporting on Tin nhanh chứng khoán on 05/10/2026, HOSE published its [margin exclusion list of 65 securities](https://www.tinnhanhchungkhoan.vn/65-chung-khoan-khong-du-dieu-kien-giao-dich-ky-quy-tren-hose-quy-iv2026-post398882.html) for the fourth quarter of 2026.
